§impl Pair
impl Pair
pub fn verify_deprecated<M>(
sig: &CryptoBytes<sp_core::::sr25519::Signature::{constant#0}, (SignatureTag, Sr25519Tag)>,
message: M,
pubkey: &CryptoBytes<sp_core::::sr25519::Public::{constant#0}, Sr25519PublicTag>,
) -> bool
pub fn verify_deprecated<M>( sig: &CryptoBytes<sp_core::::sr25519::Signature::{constant#0}, (SignatureTag, Sr25519Tag)>, message: M, pubkey: &CryptoBytes<sp_core::::sr25519::Public::{constant#0}, Sr25519PublicTag>, ) -> bool
Verify a signature on a message. Returns true
if the signature is good.
Supports old 0.1.1 deprecated signatures and should be used only for backward
compatibility.

fn public( &self, ) -> CryptoBytes<sp_core::::sr25519::Public::{constant#0}, Sr25519PublicTag>
Get the public key.
§fn from_seed_slice(seed: &[u8]) -> Result<Pair, SecretStringError>
fn from_seed_slice(seed: &[u8]) -> Result<Pair, SecretStringError>
Make a new key pair from raw secret seed material.
This is generated using schnorrkel’s Mini-Secret-Keys.
A MiniSecretKey
is literally what Ed25519 calls a SecretKey
, which is just 32 random
bytes.

optional seed, in the case that the pair can be expressed as a direct derivation from a seed
